BOX MAKING AND COVERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 294,486, dated March 4, 1884.

Application filed May 19,1883. (Nomodeh) To all whom it may concern..-

Be it known that we, CHARLES HENRY MAN- NECK, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, and WILLIAM Wrrrn, a citizenof the United States, residing at New Haven, 'in the county of New Haven and State of Con- .necticut, have invented certain new and usefacilities for the proper adjustment of the supporting-rolls, the rotary cutter, the boxblock, the box-clamp, and paper-pressing rolls, and other means h ereinafter described, and specifically set forth in the claims. We attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side View of the machine, in which the roller-supporting screws are re moved. Fig. 2 is a plan View of the machine. Fig. 3 is a front view of the same. Figs. 4, 5,

. 6, 7 represent, respectively, alongitudinal vertical section, a transverse section, a top view,

and a rear view of one of the paste-boxes and rolls connected thereto. Figs. 8, 9, 1O represent, respectively, in front view, plan, and

vertical section, the portion of the machine carrying the paper-cutters, Fig. 10 showing also a rear view of the cutters, spring-presser, and guide. Figs. 11 to 15, inclusive, repre sent the box-supporting block in vertical sec tion and in side'view, and also its component parts. Figs. 16 to 21, inclusive, represent detail views of the mechanism used for clamping the bottom of the boX against'the edges of its sides. Figs. 22, 23, 24 represent, respectively, in plan, front, and side views, the paper-pressing roller and its support. Figs. 25, 26, 27 represent, respectively, in plan, side views, and front View, a modified form of paste-box mounted upon its frame.

Similar letters refer to similar parts throughout the several views.

In said drawings, A represents a frame adapted to be placed upon a-table or upon legs, to have the operative parts within easy reach of a persons hands. Upon one end of this frame are mounted, as shown in Figs. 1 and '2, the shafts carrying rolls of paper B B, the strip upon the upper roll, B, being most commonly wider than the other. Adjoining the paper rolls there are secured to the frame Athe boxes 0 and 0, containing paste, glue, or other suitable adhesive composition, within which the paste-rolls O are adapted to revolve, their shafts being mounted in suitable journal-boxes upon the edge of the paste-boxes. To bring the strips of papers in contact with the surface of the paste-rolls, the rear end of each paste-box is provided with a transverse rod, c, under which the strip of paper is first made to pass. After passing over the paste-roll, it is desirable to remove any surplus of paste adhering to the paper, the excess varying accord ing to the consistency of the paste and the amount in the paste-box. moved by causing the pasted side of the strip of paper to rub against the acute forward edge, 0-, of the paste-box. This is accomplished in This surplusis rethis instance by passing the strip of paper un- {der aroll, 0 mounted on the outer ends of arms- ,c pivoted to lugs projecting from the pastef box, and retained connected adjustably thereto by means of screws 0. These-arms c and roll 0 being thus capable of swinging in an arc of a circle, the relative position of the strip of paper to the acute or paste-scraping edge of the box can be adjusted with great precision, according to the condition and amount of paste in the paste-box. After having passed under the rolls 0 the upper strip, B, is passed over the roll'D, while the under strip, B, is passed over the roll D,located in advance of the roll D, and it is upon this roll that in this instance the two strips come in contact with each other and become united, the edge of one strip generally extending beyond the other. To cause nearly all the rolls of the machine to run with as little friction as possiple, their shafts are carried up on conical points, forming one end of the screws 1!, secured to the frame by jam-nuts a. To cause one edge of one strip to project uniformly beyond the edge of the other during the entire delivery of a series of coiled strips without the use of guides is somewhat difficult, as the texture of one edge of either strip may differ from the other, absorb more paste than the other, and become more elongated. e aeconiplish this object by forming slots a (vertically, or nearly so) in the frame A opposite the ends of the rolls D and D, through which the conical-pointed screws a pass, and these screws a are clamped at the desired point in the slots by jam-nuts on each side of the frame, so that either end of the roller D or of the roll D can be set slightly higher than the opposite end, and thereby cause the strip or strips of paper to creep sidewise toward the higher point upon said roll or rolls. After the two strips have been united in proper relative position upon the roll D, they pass together under the roll D'", where they become bent or tempered in one direct-ion, and then over the roll D, where they are bent in the opposite direction, and from this latter roll they will pass to the box, upon which they are to remain. Said box (or simply its sides or its tube) is mounted upon a block of peculiar construction mounted upon a shaft, 0, passing through a longbearing, c, in which it can rotate, but is prevented from moving lengthwise by collars a", set upon said shaft at each end of said bearing 0'. This bearing is carried by a clamp, e, adjustably secured up the side of the frame A.

The hollow box-block E has sides that can be contracted in size to easily enter a box, and expanded again to closely fit the interior of said box. lt is made of four quarters or corner-pieces, E. (See Figs. 12 and 18.) Each quarter has secured in its interior a small rectangular plate, E provided with a dovetailed tenon, E, and the tenon of each plate is made to enter into dovetailed grooves E, pointing toward a common center in a rectangular plate, E, having four slots or large holes, E, and through these holes is made to pass with free play the screws E, to the outer end of which, is pivoted one end of the connecting-rodE, and the opposite end of each of said connectingrods E is pivoted to lugs projecting from the sides of a sleeve, E, adapted to move longitudinally upon the-shaft a, so that by moving the sleeve E a short distance away from the plate E the four quarters E forming the shell of the box-block are brought close together, and said box-block occupies less space and can be easily introduced into the box to be operated upon. The operator then slides the sleeve back toward the plate E, thus throwing the connecting-rods E at right angles to said sleeve and the periphery of the four quarters snugly against the interior of the box. The plate is secured upon the end of the shaft 6, and can revolve with it, as well as the parts connected therewith and forming the box-block. Expansion box-blocks made of segments and toggle-links operated by a sliding sleeve are, however, well known in boxmachines. To retain the bottom of the box against the box-block, a presser-rod, f, is used and kept against said bottom by positive means, the springs heretofore used for that purpose being dispensed with. To sustain the presserrod in proper position relatively to the boxblock, there is secured to one side of the frame A a horizontal rod, F, upon which is adjustably mounted a sleeve, F, carrying atright angles thereto another rod, F, extending toward the front of the machine, and upon the rod F the sleevev F is adjustably mounted. The sleeve F has preferably bolted thereon another sleeve, F, to receive the presser-rodf, and the latter is free to slide in said sleeve when not otherwise retained immovable by M the latch f as will be stated.

Upon the end of the rod f is mounted a small disk or button, f", capable of rotating thereon, being secured by a central sore w, j, and also adapted to rotate with the box operated upon. Upon the same portion of the presser-rodf is also mounted a sleeve, 1", carrying a facing-board, f, to press against the staying-strips of paper folded over the bottom of the box by the attendant. The sleeve f* has a cavity, f, at one end, to receive the stem of the button f and the nuts f placed-upon the rod f, to adjust the parts so that the face of the faeing-boardf will come even with the face of the rotary button 1 when the stem of the latter is within the sleeve. \Vithin the opposite end of the sleeve there is a tapering chamber, f, to engage with the beveled end of the latch f when it is desired to slide the presser-rod away from the box after the latter is completed. The latch f is pivoted near its beveled end to a sleeve, F", mounted adjustably upon the pressenrod f, and a coiled spring, f, secured to said sleeve, normally forces the beveled end of the latch away from the presserrod. The opposite end of the latch has a notch, f formed in its side, to straddle a pin, f secured to the presser rod supporting sleeve F*. v

To operate with this device: Supposing the presser-rod to be at a distance from the boxblock, as shown in Fig. 18, the sides of the box (and the bottom preferably placed loosely within said sides)'are placed upon the boxblock, and the operator places one hand upon the sleeve E" of the box-block, while with the other hand the operator takes hold of the rod f by means of its sleeve f 4 and brings the butpin, adjustably journaled at any desired.

angle in a bearing, 9'', forming part of a sleeve, and this sleeve is mounted adjustably upon a nearly vertical rod, 9 projecting from a sleeve, g adjustably secured upon a shaft, g extending across the front part of the machine. The ends ofthis shaft rest in journalboxes 9*, Fig. 3, that p'ass through slots (6 in the frame, and said boxes are retained at any desired height therein by clamping them in said slots between shoulders on one end of the boxes and hand-nuts g placed upon the other end. The shaft 9 carries a crank-lever,

g, to the outer end of which is pivoted the connecting-rod g and the latter is connected with one end of a bell-crank lever, 9 carrying a weight, g, to keep the presser-roll G upward when not in use. The opposite end of the bell-cranklever is provided with a bent portion, forming atreadle, g. This bell-crank lever is pivoted at 9 to an arm, A secured to the frame on the front portion thereof, so

i that when the operator puts his foot on the treadle and swings it toward the machine the connecting-rod g is elevated andthe presserroll is brought down upon the box, and its covering-strips are made to adhere firmly to the sides of the box. A brush may also be used in place of the roll G.

v The machine is also provided with means for cutting the strips of papertransversely; as follows: To the under side of two arms, A projecting from the front portion of the frame, is secured a ledger-blade, A extending across the machine. These arms A -have pendent lugs A carrying a transverse rod, H, upon which is mounted somewhat loosely (so that it can slide easily thereon) asleeve, H, that carries the rotary cutter H as follows: The sleeve H is also bored transversely to the opening fitting the shaft'H, and receives a shaft, h,

- having its forward end bent downward, or composed of two pieces set at an angle to form the .journal for the cutter H the latter being retained upon the lower end of the shaft h by a nut, h. To rotate this cutter, it is provided with a pulley, h, onthe under side thereof, around which a rope, k is made to pass to give it motion. This rope is secured at each end to arms A, extending downward from the lugs A or forming a part thereof. It passes also around small guide-pulleys h", mounted upon studs pendent from lugs h formed upon the sides of the sleeve H. To force the upper side of the rotary cutter against the under side The sleeve f is thenpushed of the ledger-blade, the rear end of the sleeve H is provided with an arm, H, secured thereto, and extending upward, and having bear- .ings h h for a rod, h, to slide through. To the upper end of this rod is mounted a small roller, h adapted to travel against the under sides of the frame. Secured upon the rod h about half-way of'its length is a sleeve, h and between this sleeve and the bearing h -a coiled spring,- h, is mountednp'on the rod h",

the rear end of ,thesleeve H, downward, and consequently the forward portion of the upper face of the rotary cutter against the under any irregular surfaces that may be thereon, caused by defective grinding.- To make up for wear of the rotary cutter, there is bearing against the rear end of the shaft h a screw, h, secured to the sleeve H. Great difficulties have been experienced in attempting to cut ture. We now overcome the difficulties by slightly tipping the cutting-edge of the rotary cutter upward toward the ledger-blade while the rotary cutter is advancing in either direction across the machine, as follows: Within the rear end of the shaft h (carrying the rotary cutter) longitudinal slots or grooves h are formed, within which the points of two screws, h, enter, taking care that the entering tip of said screw is somewhat smaller than the width of the grooves h, so as to allow the shaft h to rock within narrow limits in its socket, and thus permit the rotary cutter to also rock or tip against the ledger-blade. This tipping is caused by the hand-lever H through which the sleeve H is moved across the machine. This lever H is pivoted to the side of the way of its length with a connecting-rod, HT, pivoted. thereto at one end, and having its oppositeend pivoted to a screw or-stud, h secured to the under side of the cutter-shaft h,

in the under side of the sleeve H, (in place of the sloth", a cylindrical hole may be used, if made somewhat larger than the body of the screw 71 and permits the shaft h to rock in its bearings.

The operation of this portion of the machine is as follows: When the operator vdraws the handle of the lever H toward the frame of the .machine, the connecting-rod H acting against the screw or stud h, slightly tips its head t0- ward the left side of the machine, and the shaft h being slightly revolved or rocked thereby to one side, the portion 2 of the revolving cutter becomes higher than the portion 2, and thus ledger-blade at the point 2. When the handle of the lever H is moved away from theframe of the machine, the connecting-rod H pulls the head -of the screw h toward said lever H side of a transverse rod, A, uniting the twoside of the ledger-blade, and adapt it to follow produces a shear out against the edge of the.

so as to force its lower bearing, h and with it I damp or pasted paper with cutters of this naframe A at H", and is provided about half IIO said screw h passing through aslot, h", formed and tips the rotary cutter, so that the portion 5' becomes higher than the portion 2, and the shear cut against the ledger-blade is produced at the point z. Adjoining the edge of the rotary cutter a sponge, h, or its equivalent, is secured to a small arm, h, projecting from the side of the shaft h, to remove any paste adhering to the edge of the cutter. The hand-lever could be easily connected with a treadle within reach of the left foot of the operator by means of bell-cranks or other well-known mechanical means.

It is sometimes found desirable to have two or more paste-rolls, theunder surface of which is in the same horizontal plane, and for this reason said rolls can be placed in the same paste-box, I, as shown in Figs. 25 to 27, in which the paper-roll B is suspended under the table, and the strip coming therefrom is made to pass through a flat tube, t, forming a part of the paste-box and extending from the bottom to nearly the top thereof, and the pasted side of each strip is also in this case made to rub against an acute edge to remove any excess of paste, and under guiderolls c pivoted to. the end of adjustable arms 0, similar to those shown in Fig. 1. In front of the paste-roll C a scraper, I, is secured to the sides of the box, and carries the roller 0 upon arms 0, secured at any desired angle to the lugs formed at the ends of said scraper.
